Clients have to reject any HelloRetryRequest message that doesn't lead to a change in the ClientHello. Instead, we were rejecting any HRR that didn't select an alternative group, even if it sent a cookie, which would change the CH. The good news is that I know of no TLS servers that use or need HRRs exclusively for cookies (which are mostly useful in DTLS as a way to verify the source address). The bad news is that we poisoned the ecosystem as Go 1.12 to 1.14 will reject such HRRs. Oops, hopefully no one needed this. No tests because neither Go nor s_server support cookies. This would presumably get covered once we integrate BoGo.
